Nordic Pure MERV 12 Air Filters (2 Pack)

Almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. It is best to measure your air filter and compare the exact size to our "Actual Size" specifications. The 4-inch and 5-inch air filters often have a wider variance between the nominal and actual size, depending on the manufacturer. For example, if you are replacing a 4 3/8-inch depth 20x25x4 filter in your Honeywell unit, you should order our 20x25x5 Honeywell Replacement air filter, which measures 19 7/8 x 24 7/8 x 4 3/8 (19.63x24.88x4.38).

Nordic Pure 20x25x4 Pleated Air Filters with a MERV 12 rating are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. All Nordic Pure pleated air filters are manufactured using a heavy-duty, moisture-resistant beverage board frame, with a metal mesh support grid bonded to the pleats for extra support. MERV 12 furnace air filters are comparable to HVAC filters with an MPR rating of 1500-1900. This high-performance HVAC replacement filter will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance.

It is important to regularly change your furnace air filters, especially during any home improvements, to maintain fresh, clean air in your home or office. We recommend changing your air filter every 3-6 months to maximize efficiency and economy.

The actual size of Nordic Pure 20x25x4 MERV 12 Pleated AC Furnace Air Filters is 19-1/2-Inch by 24-1/2-Inch by 3-3/4-Inch. It is crucial to measure your filter and compare the exact size to our "Actual Size" specifications, as almost all filters are slightly smaller than the nominal size printed on the filter. This is especially important for 4-inch and 5-inch filters, as there are many different exact sizes for the various HVAC manufacturers. Your filter may state 20x25x4, but it could be the same as our 20x25x5 filter. Measuring and comparing the size ensures the filter will fit properly.

Changing your air filter is the first step in ensuring your HVAC system runs at its optimal level. Generally, you should change your 4-inch air filters every 3 to 6 months. Nordic Pure air filters are made of an electro statically-charged synthetic material that draws airborne particulates to it like a magnet, capturing particles as small as 0.3 microns. These filters do not kill germs, but the filter media does not permit the growth of bacteria or mold, so there is no need for added chemicals.

In summary, Nordic Pure MERV 12 Pleated AC Furnace Air Filters are high-performance, USA-made replacements that help maintain efficient HVAC operation and improve indoor air quality. Measuring the exact filter size and changing it regularly are crucial for optimal system performance and air purity.
